Abstract

We present an efficient, ultrafast regenerate amplifier that increases the energy of a laser pulse from 300 pJ to 6 mJ and produces average powers of as much as 9 W in a ${\text{TEM}}_{00}$ spatial mode. As an ultrafast amplifier, the system produces 4-mJ pulses with 0.09 TW of peak power.
